We also test that legacy keysend payments are promoted to AMP payments
on the receiver-sdie by asserting basic properties of the fields
returned via the rpc.
Add more fields to channel acceptor response so that users can have more
fine grained control over their incoming channels. With our chained
acceptor, it is possible that we get inconsistent responses from
multiple chained acceptors. We create a conjugate repsponse from all the
set fields in our various responses, but fail if we get different, non-
zero responses from our various acceptors. Separate merge functions are
used per type so that we avoid unexpected outcomes comparing interfaces
(panic on comparing types that aren't comparable), with casting used
where applicable to avoid code duplication.
This commit adds an optional error message to the channel acceptor's
reponse to allow operators to inform (or insult) unsuccessful channel
initiators as to the reason for their rejection.
This field is added in addition to the existing accept field to maintain
backwards compatibity. If we were to deprecate accept and interpret a
non-nil error as rejecting the channel, then received a response with
accept=false and a nil error, the server cannot tell whether this is a
legacy rejection or new mesage type acceptance (due to nil error),
so we keep both fields.
As a convenience method for users to look up what RPC method URIs exist
and what permissions they require, we add a new ListPermissions call
that simply returns all registered URIs (including internal and external
subservers) and their required permissions.
To make sure we can use the abandonchannel RPC for getting rid of
externally funded channels who's funding transaction was never
published, we allow the RPC to be used on non-dev builds for externally
funded and pending channels only.
This is useful when we wish to have a channel frozen for a specific
amount of blocks after its confirmation. This could also be done with an
absolute thaw height, but it does not suit cases where a strict block
delta needs to be enforced, as it's not possible to know for certain
when a channel will be included in the chain. To work around this, we
add a relative interpretation of the field, where if its value is below
500,000, then it's interpreted as a relative height. This approach
allows us to prevent further database modifications to account for a
relative thaw height.
Add start and end height parameters to the rpc and cli GetTransactions
endpoints. Default to returning all transactions from genesis to tip,
including unconfirmed transactions to maintain backwards compatibility.
Changes the grpc proto file, generates the protobuf, and
enables a queried way to retrieve payments in the rpc, where
backward compatibility is enforced by returning all payments
in the database by default. Adds a payment index field to
the returned payments of the rpc call.
Update the PendingChannel message from a bool to an enum to
differentiate between the case where the remote party initiated the
channel and we have no record of the channel initiator. The previous
field has not been included in a release of lnd, so we can replace the
field directly.
Move enum out of CloseSummary struct for more general use. This does
not change the encoding of the enum, and will only cause compile time
errors for existing clients. This enum has not been included in a
release yet, so we can make this move without much disruption.
There is an alternative in routerrpc now. It doesn't support REST yet,
but the main rpc SendPayment with its bidirectional streaming isn't
usable via REST either.
SendPaymentSync still serves REST users and cannot be deprecated yet.
